Abstract: According to the climatic characteristics and the forage planting needs in Songtao Miao autonomous county of Guizhou Province, intercropping experiments were carried out with Qianyu No. 1 chicory, Beilin No. 202 alfalfa and Qiancao No. 4 cocksfoot, respectively. The yield-increase benefit of intercropping mode of Qianyu No. 1 chicory with different varieties of forage was assessed by comparing and analyzing the yield, nutritional quality and production efficiency under intercropping or monocropping condition. The results showed that the annual yield of fresh grass was 87.27 t/hm2 when Qianyu No. 1 chicory was intercropped with Beilin No. 202 alfalfa, which was increased by 36.17% compared to the monocropping of alfalfa; the yield efficacy was improved by 20.77%, and the protein content was 26.83%. The results obtained in this study may provide technical support for the development of the grasslands and animal husbandry industry in this region.

Key words: Qianyu No.1 chicory, alfalfa, cocksfoot, intercropping, monocropping
